The present invention provides a continuous production method of hydrogen which is able to producehydrogen, which is clean energy, simply and continuously without using ammonia. The invention of the continuous production method of hydrogen includes a hydrogenproduction step comprising introducing mayenite (Ca12Al14O33) and calcium hydroxide [Ca(OH)2] into water and allowing them to react with water, thereby generatinghydrogen and also forming katoite [Ca3Al2(OH)12]; a regeneration step comprising baking the formed katoite to regenerate mayenite and calcium hydroxide; and a circulation step comprising returning the regenerated mayenite and calcium hydroxide into the hydrogenproduction step. It is preferable that a temperature of water in the hydrogenproduction step is from 50 to 100° C., and a molar ratio of mayenite to calcium hydroxide is 1/9. In addition, it is preferable that a baking temperature of katoite in the regeneration step is from 300 to 500° C.

For generatinghydrogen particularly for feeding a fuel cell, liquid solutions (4, 5) of a chemical hydride and of a accelerator or pre-accelerator are fed to a reaction site (11, 12, 13) via a peristaltic pump (9) and thereby commingled at a constant mutual ratio and so that the control of the reaction that leads to the release of the hydrogen can be conveniently performed by varying the pump speed and the duty cycle of a start and stop operation of the pump, while also regulating the temperature and the pressure at the reaction site.

A method of operating a hydrogengenerator includes: a step (a) of generating a hydrogen-containing gas by a hydrogengeneration unit by using a raw material in the hydrogengeneration unit; a step (b) of removing a sulfur compound from the raw material by a hydrodesulfurizer which is heated by heat transferred from the hydrogengeneration unit; and a step (c) of performing an operation of supplying the raw material to the hydrogengeneration unit after stopping the generating of the hydrogen-containing gas by the hydrogengeneration unit. The step (c) is not performed unless, at least, a temperature of the hydrodesulfurizer is such a temperature at which carbon deposition from the raw material is suppressed.
